The gentle formula soothes irritation and restores the balance of the scalp's microflora without stripping or drying out the hair.Application: Use daily until the scalp is clear and then at regular intervals as required. Apply to wet hair and lather, gently kneading the scalp for 60 seconds. Rinse well and repeat if necessary. Follow with the matching Philip Kingsley Conditioner and Toner for flaky/itchy scalps.
